What is a normal GGT level?

Answer

The normal GGT level in a person's body varies with sexes where in a woman, the normal level is 0 - 45 U/L while in a man is 0 - 65 U/L. GGT is a liver enzyme which is responsible for the transportation of amino acids and peptides into cells as well as glutathione metabolism. This enzyme is particularly sensitive to alcohol use.
